Explore how Bionano technology works

The Bionano Genome Imaging workflow starts with mega-base size DNA isolation. A single enzymatic reaction labels the genome at a specific sequence motif occurring approximately 15 times per 100 kbp in the human genome. The long, labeled DNA molecules are linearized in nanochannel arrays on a Saphyr chip® and imaged in an extremely high throughput, automated manner by the Saphyr® Genome Imaging Instrument. Using pairwise alignments, the molecules are assembled into local maps or whole genome de novo assemblies. Changes in patterning or spacing of the labels are detected automatically, genome wide, to call all structural variants.
